Specification of Letters Patent.

Patented March 6, 1906;

Application filed July 13,1905. Serial No. 269,535.

To alt whont it may concern:

Be it know that we, Jenn C. AsonENnAon and Josnrn W. AsoHENBAcH,citizens of the United States, residing at Philadel hia, in the countyof Philadelphia and tate of Pennsylvania, have invented certain new anduseful Improvements in Lam s; and we do declare the following to be alidi, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to ineke and use thesame.

Our invention relates to improvements in lamps, and more particularly tolamps for carriages and other vehicles.

One object of the invention is to provide means whereby oarriagedamps ofthe ordinary construction now on the market may be readily adapted forburning either. oil or candles, as desired.

Another object of the invention is to so construct the lain that asteady and uniform flow of air wi be supplied to the flame, so that thelamp will burn with the greatest brillianey and without danger of beingcasually blown out.

Another object of the invention is to im prove and simplify theconstruction of lam s of this character, and thereby render t e samemore durable and efficient in use and less eX ensive to manufacture.

Wit the above and other objects in view the invention consists ofcertain novel features of construction, combination, and arrangement ofparts, as will be hereinafter descri ed and claimed.

In the accompanying drawings, Figure 1 is a side elevation with parts insection of the lower portion of a carriage-lamp with our improvementsapplied thereto, the parte of the lamp being adjusted i or burning acandle. Fig. 2 is a vertical sectional view through the same. Fig. 3 isa view similar to Fig. 1, showing the arts adjusted for burning oil inthe lamp. ig. 4 is a vertical sectional view through the parts shown inFig. 3; and Fig. 5 is a erspective view of the telescoping tubes,sliowing the manner in which the inner one is adjusted.

Referring to the drawings by numeral, 1 denotes the base or bottom of acarriagelamp oi the ordinary or any preferred form of construction. Asshown, said bottom is slightly (lished and has upon its u per side theusual lining 2 and upon its un( er side a collar-ball 3, which may besecured by solder, serews, or in any other suitable manner.

Projecting through openings in the lining Z and the bottom or base i isa eonehood 4, which has its large open bottom bearing upon the innersideof the collar 3 and its open upper end dis osed concentric with aguidetube 5. The iiitter projects through the collar 3 and has upon itsouter side screwthreads 6 to receive the usuai detachable basetube 7,which serves as a closure for the lower end of the guide-tube.

Mounted to telescope within the guidetube 5 is an inner tube S, withinwhich may be supported an illuminating element 9, which may be either inthe form of a candle 10, as shown in Figs. 1 and 2 or the drawings, orin the form or an oil-lamp 11, as shown in Figs. 3 and 4. This slidinginner tube 8 has upon its upper end an inwardly-projnoting annularshoulder 12, which is formed, preferably, by an apertured oep, which issecured as shown.

W'hen it is desired to burn a candle in the y lamp, the inner tube 8 isadjusted vertically in the tube 5. so that the cap 12 closes the openingin the top of the cone-hood 4. tube 8 is retained in this position bymeans of a coil-spring 13, which feeds the candle upwardly against theshoulder or cap i2. This spring 13, as shown, is covered by a fabriccovering 14 and is disposed within the tubes S T, as shown, one of itsends bearing against the bottom of the tube 7 and its opposite end beingsecured to a follower 15, which is adapted to engage the bottom of thecandle 10 and slide in the tube S. Vlhen it is desired to burn oil inthe lamp, the candle 10 and spring 13 are removed and replaced by theoil lont or reservoir 16 and its attached burner 1?, and the inner tube8 is moved downwardly into the guide-tube 5, so that necessary draft ofair may pass between the cone-hood 4 and said tubes, as indicated by thearrows in Fig. 1i of the drawings. The adjustment ol' the inner tube 8in the guide-tube 5 may be eileeted in any desired manner; but wepreferably provide upon the tube 8 a projection or stud 18, which slidesin a slot 19, formed in the lower end of the tube 5. When the tube S isin its elevated position, (shown in Fig. 2,) said projection 18 isseated in the upper end of the slot 19, and when in its lower position(shown in Fig. 4) said projection is engaged Said with the bottom of thetube 5, so that said tube and the attached lamp will be firmly connectedto the tube 5. It will be understood that the tube 8 when it is loweredis dle, may be of any desired form and construction and may be securedin the tube 8 in any suitable manner. As shown in Figs. 3 and 4 of thedrawings, the oil font or reservoir 16 is in the form of a tube orcylinder, which is adapted to be inserted through the open lower end ofthe tube 8 and which is retained therein by screwing the burner 17 downinto the screw-threaded opening in the top of the reservoir 16, so thatthe two parts will be clamped 4upon the shoulder or cap 12, as clearlyshown in Fig. 4. The burner 17 is of such size that sufficient space isleft between its top and the opening in the top of the cone-hood 4 whenthe tube 8 is in its lowered position to permit a draft of air to passupwardly to the fiame. The stem 20 of the ratchet-wheel, which raisesand lowers the wick of the burner 17, is adapted to project through aslot 21, formed in the rear side of the cone-hood 4 adjacent to itsupper end, so that said burner may be readily inserted in the conehoodthrough the opening in its top. In order to provide a steady and uniformdraft of air for the lamp, the collar 3 is formed adjacent to its lowerend with an annular series of apertures or perforations 22, and withinthe space between the tube 5 and conehood 4 are provided an air-spreader23 and a partition-plate 24, of foraminous or reticulate material. Thispartition, as shown, is in the form of a perforated or apertured ringsecured to the upper end of the tube 5 and to the interior of thecone-hood 4 by solder or in any other suitable manner. The air-spreader23 is in the form of an inverted cone,which is slightlv dished and issecured upon the tube 5, so t iat it causes the air entering through theopenings 22 to take a circuitous course through the device, as indicatedby the arrows in Fig. 4 of the drawings. This spreader, together withthe perforated rin or partition 24, breaks up sudden puffs o' wind andcauses a steady uniform draft of air to be supplied to the lamp-burner.

The construction, use, and advanta es of the inventionwill be readilyunderstoo from the foregoing description, taken in connection with theaccompanying drawings. It will be seen that the lamp may be quickly andeasily adapted for burning either candles or oil and that in either casea simple, durable, and efficient construction is provided.

It will be understood that these improvements may be applied to lamps ofany kind,

lamp is provided.

While we have shown and described the preferred embodiment of ourinvention, it will be understood that we do not wish to be limited tothe precise construction herein 4set forth, since various changes in theform,

proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention.
